ICAO is also due a score card on how the bureaucratizing of aviation is coming along
Does a UN agency ever achieve anything? Sully has handed in his notice after six months.

Well, it's nice to know that I've been living under a rock . . . . had not previously seen news of Amb. Sullenberger's resignation.

In fairness to ICAO - I mean as an organization or entity, and also a place where many dedicated people at all levels devote much effort - it predates the UN. The Chicago Convetion of 1944, its Annexes, the SARPs and much more, have contributed greatly to the safety, efficiency, and overall vitality of civil aviation sectors in many countries (I mean, Member States) and internationally. Of course it's within the UN umbrella today, but that shouldn't be the reply to all interest in its work or proceedings.

I have no idea why, exactly, the Ambassador has tendered a resignation. Perhaps it is because within the past several years, the Organization has seemed captivated, or maybe "captured, occupied and indentured" is more accurate, to certain aspects of climate change orthodoxy - while at the same time proving feckless against actual present-day aviation matters (RyanAir diversion, Ukrainian Int'l shootdown, MH17, to name some prominent cases). Plus it evidently is lacking anything like cutting-edge, insightful developmental work on preparing to cope with the coming onslaught of en masse cockpit automation (and ATM automation, and higher airspace traffic and usage, and AI . . . .) at least as well as global civil aviation coped with, say, the arrival of the Jet Age, the arrival also of wide-body aircraft (massive traffic growth) and two-engine overwater ops, you know, the pre-Instagram stuff.

This isn't to say that dealing with concepts, and terminology or phrasing within formal certification regulations, about levels of aviation skills, knowledge and abilities would be a subject matter where ICAO could or should take the lead. But at the same time, I think if and when a solution, at least a workable solution from an operational as well as engineering standpoint, finally is found, it would be better by far if ICAO and its various outputs were in alignment.

Cognescenti will recognize the source for this line, but I'm exercising caution in stating attribution; an airline enmeshed at the time in a matter of international civil aviation diplomatic controversy claimed its operations were "the business of freedom." There is something to that notion. Maybe a lot of something. Anyhow, and much to this attorney-and-SLF's disappoinment, the upcoming Assembly in Montreal just won't be the same without the class, eminence and integrity brought to the role of U.S. Permanent Rep.

We try to design for the lesser skilled pilots, but you need to draw the line somewhere or we'll never be able to certify a piloted aircraft.
I agree that "average", "must not require unusual skill" and the like are very difficult to quantify. But there has to be a starting point somewhere. For my experience, if the pilot assessing the handling characteristic has any doubt about compliance, the first thing he/she does, is discuss it with the team, including the certifying authority. This would be the opposite of murmuring to one's self that it's "probably okay" and saying nothing, knowing that doing so steps the certification process along.

I have certainly trained pilots on airplane types which I knew to be totally benign, and the pilot had a terrible time with it - it was the pilot! And, I own a certified single engine GA type, which is so demanding of skill, it is actually actually requires a type rating in other countries. In my opinion, it does demand unusual skill, and type specific training, but it was certified "normally".

In any case, like anything in certification, if in doubt, report and discuss (then probably have another pilot assess, with the concern in mind).

I agree, it's not 100% avoidable to have some vagueness, in the end, flying is (for the foreseeable time) a human driven process.

However, striving to minimize the amount of vagueness could be very useful.

Engine failure at V1 controllable can be specified in maximum flight-path/3D-position/energy deviations vs. time, given a maximum amount/reaction-time of control input.

Compare this with EGPWS. EGPWS effectively creates a dynamic multidimensional "virtual-path", where it is safe to fly. As long as the aircraft stays within these multidimensional boundaries, the aircraft is safe. Move outside this virtual-path and the dangers start adding up, sometimes very quickly.

For the V1 failures, a similar virtual-path can be defined and used as a certification requirement. Define the maximum amount of correction required, vs. the reaction time, and things do get quite deterministic. This would immediately wipe out the possibility that an outright dangerous aircraft will pass the certification tests (because with the vague certification criteria, an ace could save the aircraft certification). This way, you create "a ruler" to be used for the certification. When the current certification criteria were established, technology wasn't available to specify and/or measure this type of specifications, so, one did water down these certification criteria to "average pilot", etc. Nowadays, math, computational power as well as sensor capabilities are an order of magnitude better and a different, less vague, approach to certification would be feasible.

And, because the aircraft certification gets deterministic, the pilot certification can also become more deterministic. Still not perfect, though getting better than the vague "average" qualification.

The bold part is the problem. As long as one is dealing with honest people, things are fine. The moment greed sets in, we get what happened to the MAX. Have less vague certification specifications and the amount of cheating will be reduced.

Initially, this sounds pretty bad for aircraft designers, though looking further into this, it makes their life a lot easier. Engineers/Technical designers want to have clear criteria of what they need to achieve, and makes preparing for the certification a lot easier. Not to say, for example, the whole car-industry works on these principles. Turn the vague marketing level requirements into technical requirements and create the technical design from there. Once the technical options are exhausted, work with the marketing to update (maybe water down) the marketing goals for that specific item. Since cars are produced in massive amounts, this working mechanism is mandatory to avoid disaster designs.

Just as an aside, I’ve never forgotten that many (MANY!) years ago as an IFALPA rep at an ICAO Airworthiness Committee meeting, I worked with a terrific character named Thomas (Tom) Foxworth who was the relevant ALPA committee chairman. We were discussing reaction time for accelerate-stop certification and apropos what “quality” of pilot should be fed into probability models etc, Tom used the phrase “least competent of the competent” to encompass both the pilot who regularly just scraped by on all training, and the one who did pretty well but was at the low end of e.g. fatigue on the day.

In a very safe, yet still evolving industry, the processes required to maintain the highest standards also have to change. The difference between the old and new views of safety (human error) is a simplified example.

Outwardly the FAA and Boeing holds the old view, ‘blame and train’. Build systems assuming that it is possible to sufficiently train people - change human nature - to manage foreseeable situations; thus taking the greatest credit for human performance in system operation - malfunction. (Outwardly Airbus appears to differ - safety attitude - integrated systems; EASA less convincing?)

With evolution, safety depends on recognition that human activity and particularly training is limited, with increasing uncertainty in outcome. Certification decisions via requirement and consensus must now be seen as soft judgements which accommodate the widest range of views and (unforeseen) situations. This in part represents the new view; complex operations depend on human activity, the human is an asset, but limited by the situation.
Certification processes in complex system need greater focus on assumptions and ambiguities, on the situational uncertainties which crews are expected to manage; aviation is slowly adapting, but perhaps not as fast as other industries. 20 yrs ago aviation was the benchmark, HF, CRM, risk management; nowadays aviation appears to lag other transport systems and medical care. In many ways aviation is complacent, slow to change, reluctant to view the world differently.

Boeing hasn’t delivered a 787 in more than a year and now the latest kick in the arse

[QUOTE][[color=#222222]The U.S. Department of Transportation (DOT) Office of Inspector General (OIG) has announced plans to audit of the FAA’s oversight of Boeing 737 and 787 production. According to a memorandum released by the OIG, the audit will focus on the FAA’s process for “identifying and resolving production issues and addressing allegations of undue pressure within the production environment.” The audit is expected to begin in July./QUOTE]

You would think that by now Boeing execs would have made sorting the production process issues a high priority starting with getting serious about encouraging a robust safety reporting culture, yet the steady drip drip of own goals continues. I think that sadly, Boeing is too broken to fix….

6 months....hm. I feel that ICAO isn´t what it used to be. Doesn´t seem to have enouth people, resources and attention by politicians who expect it to play it´s vital role in aviation. Check this out:
https://www.icao.int/annual-report-2...2021-2022.aspx
Quote:
The budget is a Zero Nominal Growth (ZNG) budget, developed by maintaining the average Assessment of Member States for the next three years at the 2019 level, while retaining all important existing activities and providing additional resources for priorities such as aviation security, Carbon Offsetting ((( plus plus plus....)))
Easy to see that ´´traditional´´ ICAO work is put on hold to cater for fancy (though needed) new projects. However, we need a solid basis for Aviation.... Echos of the Boeing management mess ??
Whatever, I can understand Sully.

Boeing corporate has been single-minded in doing nothing much to reverse the rot that arose from the MDD invasion of TBC. If they didn't get the message over the tanker debacle, the B737 ring frame saga, the 787 section joints, the Max, and production in the Carolinas, along with the tanker fuel debris etc... apparently the lads are inured to "signs". Moses, they ain't. Boeing doesn't however need a prophet, they need a leader that places quality higher on their agenda than bloated profits (prophets?) They have had more than a few hints to amend their ways, but seem to have the pioneer spirit to keep on in spite of common sense.,

Time to dislodge the board.

I think, it is dangerous to insist on "quality", since this emphasizes "paperwork", which is already available in large quantities at Boeing, though watered down (because of the sheer volume), by those in charge to control the operations are performed according "the books".

What Boeing needs is the reverse to the concept of technical excellence as a leading item. And the understanding that long-term profits only come from the fruits of this technical excellence.

But, hey, this is how all big companies in the end start to fail.

Boeing produces both products and services. The client for any of their output makes a determination on the output based on quality and price, which is the basis of economic differentiation in the marketplace. The term Quality in that sense is not the narrow view of a QA program, it is what the output is considered by the purchaser to be fit for, and it occurs in a comparative space. If the alternative is an AN-2, then the B7XX may be attractive, warts n all. If Boeing is being compared to another competent provider, say one starting with the first letter of the alphabet, then when the products seem to be messed up in the kitty litter routinely, and over 25 years of the input from MDD manglement, it appears this is business as usual or business as desired. That's the quality matter that a purchaser looks at. Price can always be made so attractive that the purchaser's shareholders will have kittens (who don't mind the kitty litter surprises) if the customer doesn't take advantage of the short term gains in discounted products. The OEM's QA department is a part of the quality case, but is just a part. Not caring about your product certainly makes pricing a factor, like the AN-2.

Gotta start somewhere, and that means probably at the top, they are the ones with the remit to take action. It is conceivable that the engineers and machinists and QA staff of the company could stage a mass walkout, but then it is quite possible that the mgt would care less, they probably can book an improved balance sheet due to the reduction in labor costs, grab their stash 'o cash and retire.

There was a time when we used to be proud of driving Boeing aircraft. Boeing still made hashes occasionally, like JAL 103, but then so did everyone, (DC-10 door locks... L-1011 CWS... Airbus rudder limiter design... vertical stab secondary structure...) Would be nice to have pride in their product.


PS: the AN-2 is actually a pretty neat plane in its own right,

Boeing are the product owner.

They cannot in any meaningful sense outsource decisions on the safety or suitability of the product to their customer.

The problem we saw recently with MAX is precisely that they were suckered into doing just that.

It doesn’t work. It has no longevity.

You enquire about your customers’ opportunities and constraints. You don’t ask them to define the solution. That isn’t a customer responsibility.

Succumbing to the lowest common denominator of your client requests, outsourcing your product definition to your client is just a death spiral.

What they actually have to do is figure out how to be justifiably proud enough of their product that they are prepared to fire the customer.

If they can get that right, they won’t have to.

Well.... Not exactly. "The client" may make a determination of the output quality, it is their contractual right, should they choose to exercise it. More commonly, the client depends upon the conformity of the product with an approved type design. The authority (in this case, the FAA) has issued that type approval based upon demonstration and finding of design compliance to national or international design standards. The client need not be solely responsible for making a determination of quality, it could be a task beyond their internal technical capability - they depend up the authority for that service to society.

The authority (in this case, again, the FAA) has delegated some of the approval task, of finding of design compliance, to Boeing. Boeing is bound by commitment to the FAA to exercise that delegation ethically - not to find compliance when it has not been demonstrated (the product is not actually compliant). Of course, Boeing is a corporate entity, not a person, so it depends upon people to be ethical in the exercise of the FAA delegation for finding design compliance, and contributing to the FAA's type certification of the product. Every person who is associated with the demonstration and finding of design compliance has an ethical duty to not represent [to the FAA] that compliance has been demonstrated, when it has not. Isn't it fraud when a person (or corporate entity) makes a representation to achieve an outcome, when the representation is false?

25.1309(2)(c):

Warning information must be provided to alert the crew to unsafe system operating conditions, and to enable them to take appropriate corrective action. Systems, controls, and associated monitoring and warning means must be designed to minimize crew errors which could create additional hazards.
A person in the employ of Boeing either made, or led the FAA to make, a finding of compliance that the MCAS system met the foregoing design requirement. Did the MCAS produce a warning to alert the flight crew to an unsafe condition (its failure)? From what I understand, the warning system was an option, which only a few airline customers purchased. The design requirement does not allow the warning system to be optional! It's required for compliance to be found - but, design compliance was found for airplane which did not include the warning system - someone signed for something which was not there. I imagine that a Boeing test pilot would know of this design requirement, and should speak up when he joins the dots that a required, not pilot controlled, stability system could fail, and there be no crew warning. If a person signs for the compliance of a required system which is not present, to gain [approval], isn't that fraud?

MCAS did not fail. The AoA subsystem did, producing erroneous data and a false stall warning. MCAS did exactly what it was supposed to do based on the information it was provided. Isn't the suggestion for pilots to push the nose down when there is a stall warning and stick shaker? While MCAS wasn't designed to detect or react to stalls, and appears to have no such input, it is supposed to provide a correction to a high AoA and it did. The FAA, Boeing, foreign CAAs, and all pilots trained on the 737 NG already accepted the chance for a false stall warning and had done so for, estimating, 2 decades.

Hi BBT,

From a regulatory perspective, the TC holder wears the hat for the program quality as a compliance matter to the regulation framework. The customer has choices, and can elect to make their determination of an acquisition based on the value of the product that is provided to them which is quality v pricing. The AN-2 can look attractive in it's own way. Is the product that is offered at present achieving a desirable acquisition to those that have choices?

MCAS did fail because it had been made dependent on single data point input from AoA-systems and data interpretation not being reliable enough.

Are false alarms are OK? Wasn't it the startle effect from the false alarm that caused the ET302 crew to ignore that full thrust remained as the plane exceeded the velocity envelope? Wasn't it the false alarm that forced the autopilot to go offline and allow MCAS to operate?

I prefer to focus on the origin of the problem and not the edge of the last chance to correct it.

Why wasn't the autopilot software designed to choose the correct AoA sensor? Why when it went off line didn't the autothrottle also go off line? These are also decades old decisions. Why is the AoA sensor not fail-safe? But, sure, multiple decades of depending on all these bad ideas.
